[0024] like Figure 1-3As shown, the PVC sheet loading and pallet turning device comprises an L-shaped turning device 1, one side of the L-shaped turning device 1 is provided with a fixing mechanism 2 for pressing and fixing the PVC sheet from top to bottom, one side of the fixing mechanism 2 is provided with an auxiliary mechanism 3 for fixing and reinforcing the PVC sheet, the fixing mechanism 2 comprises a screw 204, a sliding block 205 is threadedly mounted on the outer wall of the screw 204, a fixing plate 206 is mounted on the right side of the sliding block 205, and a motor 207 is mounted on the top of the screw 204. In this embodiment, when in use, firstly place the PVC sheet with the pallet on the fixing mechanism 2, and then start The motor 207 is driven to drive the screw rod 204 to rotate, and the sliding block 205, with the cooperation of other parts of the fixing mechanism 2, moves longitudinally, drives the fixing plate 206 to move longitudinally, and drives the auxiliary mechanism 3 to contact the upper surface of the PVC sheet, and presses the PVC sheet from top to bottom and fixes it on the parts of the fixing mechanism 2. The L-shaped flipping device 1 is started to drive the fixing mechanism 2, the auxiliary mechanism 3 and the PVC sheet to flip 90 degrees together, and adjust the position angle of the PVC sheet, so as to fix the PVC sheet with a pallet, prevent the PVC sheet from offset during flipping, causing the PVC sheet to slip and cause damage to the PVC sheet.

[0025] like Figure 1-3 As shown, the fixing mechanism 2 also includes an L-shaped plate 201, which is installed on the L-shaped flipping device 1. A rectangular notch 202 is provided on the right side of the L-shaped plate 201, and a connecting block 203 is installed on the top side of the L-shaped plate 201. A screw 204 is rotatably installed in the rectangular notch 202, and the screw 204 is rotatably installed on the L-shaped plate 201 and the connecting block 203. A motor 207 is installed on the top side of the connecting block 203, and a sliding block 205 is slidably installed on the connecting block 203 and the inner wall of the connecting block 203. In this embodiment, the motor 207 is stably supported by the connecting block 203, and the inner diameter of the connecting block 203 corresponds to the rectangular notch 202 to extend the sliding height of the sliding block 205, and the connecting block 203 is moved under the drive of the screw 204. The position is limited to avoid rotation with the rotation of the screw 204, thereby improving the stability of the fixed plate 206 pressing and fixing the PVC plate from top to bottom.

[0026] like Figure 1-3As shown, the auxiliary mechanism 3 includes four connecting columns 302, and four circular holes 301 are penetrated on the top side of the fixing plate 206. The connecting columns 302 are slidably installed on the inner walls of the circular holes 301. Springs 303 are sleeved on the outer walls of the four connecting columns 302. A resistance plate 304 is installed on the bottom side of the four connecting columns 302. In this embodiment, when the fixing plate 206 moves downward, the resistance plate 304 is driven to move downward, and the resistance plate 304 contacts the PVC sheet. As the fixing plate 206 continues to move downward, the connecting columns 302 slide in the circular holes 301, and under the cooperation between the resistance plate 304 and the fixing plate 206, the spring 303 is compressed, so that the resistance plate 304 fits tightly on the PVC sheet, thereby enhancing the stability of fixing the PVC sheet.

[0027] like Figure 3 As shown, four circular holes 301 are respectively arranged at the corners of the fixing plate 206 and are symmetrical to each other. In this embodiment, through the position setting of the four circular holes 301, when the contact plate 304 reinforces the PVC plate, the force points are uniform, thereby improving stability.

[0028] like Figure 1-3 As shown, the length and width of the abutment plate 304 are equal to those of the fixed plate 206, and the length and width of the fixed plate 206 and the abutment plate 304 are the same as the length and width of the upper surface of the L-shaped plate 201. In this embodiment, the length and width of the L-shaped plate 201, the fixed plate 206 and the abutment plate 304 are set so that the PVC plate is pressed and fixed from top to bottom, and the contact area is constant, thereby improving the stability of the pressing and fixing.

[0029] like Figure 1-3 As shown, a friction pad is installed on the bottom side of the contact plate 304, and the friction pad is made of rubber. In this embodiment, by setting a friction pad made of rubber on the bottom side of the contact plate 304, the friction resistance of contact with the PVC sheet is increased, the stability of fixed fit is enhanced, and wear on its surface is avoided.

[0030] In summary, when in use, first place the PVC sheet with the tray on the fixing mechanism 2, then start the motor 207 to drive the screw 204 to rotate, and the sliding block 205, with the cooperation of other parts of the fixing mechanism 2, moves longitudinally, drives the fixing plate 206 to move longitudinally, and drives the auxiliary mechanism 3 to contact the upper surface of the PVC sheet, and presses the PVC sheet from top to bottom and fixes it on the parts of the fixing mechanism 2, starts the L-shaped flipping device 1 to drive the fixing mechanism 2, the auxiliary mechanism 3 and the PVC sheet to flip 90 degrees together, adjusts the position angle of the PVC sheet, thereby fixing the PVC sheet with the tray to prevent deviation during flipping, causing the PVC sheet to slip and cause damage to the PVC sheet, and stably supports the motor 207 through the connecting block 203, and the inner diameter of the connecting block 203 corresponds to the rectangular notch 202 to expand the sliding height of the sliding block 205, and the connecting block 203 is moved under the drive of the screw 204. The position limit is prevented from rotating with the rotation of the screw 204, thereby improving the fixing plate The stability of the PVC sheet is pressed and fixed by 206 from top to bottom. When the fixing plate 206 moves downward, the contact plate 304 is driven to move downward accordingly, and the contact plate 304 contacts the PVC sheet. As the fixing plate 206 continues to move downward, the connecting column 302 slides in the circular hole 301, and under the cooperation between the contact plate 304 and the fixing plate 206, the spring 303 is compressed, so that the contact plate 304 is tightly fitted on the PVC sheet, thereby enhancing the stability of the PVC sheet. Through the position setting of the four circular holes 301, when the contact plate 304 reinforces the PVC sheet, the force points are uniform, thereby improving the stability. Through the length and width setting of the L-shaped plate 201, the fixing plate 206 and the contact plate 304, the PVC sheet is pressed and fixed from top to bottom, and the contact area is constant, thereby improving the stability of the pressed fixation. By setting a friction pad made of rubber material on the bottom side of the contact plate 304, the friction resistance of the contact with the PVC sheet is increased, thereby enhancing the stability of the fixed fit, while avoiding wear on its surface.
